TO ALL WIIOM I'I MAY CONCERN:

Beit known that I, C. G. HOWELL, of Corning, in the county of Steuben, and State of New York, have invented a new and improved Apparatus for Distilling and Refining Petroleum and other Liquids; and I do hereby declaro that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

lhis invention relates to the manner in which the heat is applied in the distillation of petroleum and other liquids, and the invention consists in applying the heat directly, and also by steam, and in the manner hereinaft-cr described.

Figure l represents a vertical longitudinal central section of my apparatus.

Figure 2 is an end elevation of the same.

Figure 3 is a. detached View of the distilling-retort.

Figure 4-is a cross-section ofthe retort through the line a: a: of iig. 3.

Similar letters of reference indicate like parts.

A represents the arch or lmason-Work, in which the steam boiler is placed. B is thc steam boiler.v C is :the retort. D is the receiving-vessel or heater, surrounded by the heated products of combustion. E is'the crude petroleum reservoir or tank. F is the condenser. The retort C is placed in the steam boiler, substantially as seen in the drawing, and so that it is surrounded by steam, and consequently it cannot be raised to any higher temperature than the steam itself. The crude petroleum is forced into the heater D by a forccpump, where it is heated, and by the heat expanded and raise/d up through the pipe a into the retort. The crude oil is also purified, `in a great measure, in the heater by thc action of the heat, the larger portion of the rcsiduu'rn settling to the bottoni of the vessel, from which it is drawn off through the faucet Z1. 'It is designed that th'e crude oil shall iill the retort to the line marked c in the drawing. The residuuni remaining in the oil l is deposited in the bottom of the retort, and is drawn oil` through the faucet cl. The vapor ascends from the retort through the pipe f, which passes into the smoke-stack, where, for a short distance, it is surrounded by the heated products of combustion, as seen in the drawing. From the smoke-stack the vapor is conducted into lthe condenser E, which is kept lled with cold water. g is the vapor-gauge, and t is the oil-gauge. I

lof :other liquids.

'lhe steam boiler represented in this example of my invention is a common two-flue boiler, but the tubular boiler muy be used with equal success. I do not confine myself` to any particular kind of steam boiler, nor t0 vthe distillation of petroleum alone. The apparatus may be applied with success in the distillation and reduction J represents the water-line in the boiler. K is the steam-chest, with safety-valve attached. The steam Vgenerated may be used for driving an engine, or for other purposes. p

I do not conne myself to any particular form or size of retort. In adapting my method to various kinds of steam boilers, it would of course be necessary to vary the form ofthe retort. Nor do I confine myself` to the particular arrangement of the heater in reference to the boiler and retort, or ot the tank and condenser.

Havingthus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

Distilling, refining, and reducing petroleum and other liquids bythe direct action of heat to the heating vessel D, and by the action of steam en a retort placed inv a steam boiler, substantially as shown and described.

C. G. HOWELL.
